Abstract

Electro Chemical Discharge Machining (ECDM) is an emerging technique in precision machining of non-conducting materials. This hybrid machining process combines the principles of Electric discharge machining and Electro-chemical machining. The current paper discusses usage of ECDM along with a case study on machining soda lime glass, wherein the ‘Tool Wear (TW)’ and ‘Material Removal (MR)’ were studied for two different tool materials— ‘copper’ and ‘stainless steel’. The electrolyte used was NaOH. Using design of experiments and L—4 orthogonal array, it was experimentally found that all the parameters selected were significant. The TW in copper is high as compared to stainless steel and the MR is affected maximum by the applied voltage followed by electrolyte concentration.
